Best for
  • Developers looking to integrate document conversion into AI agents or MCP clients like Claude Desktop.
  • Teams needing PDF-to-Markdown/JSON conversion for RAG or knowledge management.
  • Users with access to Docling Serve or wanting hybrid mode with local fallback.
  • Hevy PRO users who want AI assistants to directly access their workout data
  • People who prefer using MCP clients like Claude, Cursor, Codex for fitness tracking
  • Anyone needing summaries and insights from their training data
Not for
  • Pure document conversion users who do not need MCP integration (can use Docling directly).
  • Scenarios without any AI agent or MCP client.
  • Lightweight single-shot conversion with no caching requirements.
  • Users without a Hevy PRO subscription (API key required)
  • Users who want to use the server without an API key
  • Those needing delete workflows (Hevy API does not expose delete endpoints)
Required permissions
  • Read local files (access PDFs for conversion).
  • Network access (required for remote mode; optional for local mode).
  • Environment variables (must set DOCLING_MCP_* variables).
  • Storage permissions (for saving generated documents or caching).
  • Requires HEVY_API_KEY environment variable for Hevy API authentication
  • Can create, update, and replace workouts, routines, folders, templates, and body measurements via tools
  • Read operations can fetch workouts, routines, folders, templates, history, and user info
Risks and side effects
  • Remote mode depends on Docling Serve; unavailability or high latency can cause failures.
  • API keys may be abused if leaked; handle with care.
  • Local conversion mode relies on system resources; large documents may cause high memory usage.
  • OCR and table structure detection may produce inaccurate results; verify outputs.
  • API key can be misused if leaked; do not expose in URLs, logs, or screenshots
  • Create operations may produce duplicates on retry; update operations replace existing records
  • The server sends data to the Hevy API and may send telemetry to external services unless disabled
